La cage (10) est ensuite garnie d'une substance déclenchant la croissance osseuse, telle que de l'os spongieux. Lorsqu'une paire de ces cages (10) sont implantées entre des vertèbres adjacentes (94, 95), les patients sont en mesure de s'asseoir sans douleur dès le deuxième ou troisième jour, bien plus tôt que cela n'était possible dans des soudures spinales antérieures en dehors de celles mettant en oeuvre des plaques d'acier et des vis. Enfin, la croissance interne de l'os à travers les perforations (13) dans le creux (14) du filetage (12) de la cage de soudure (10) forme une interconnexion permanente entre les deux structures osseuses (94, 95).

Abstract: A method for genetically engineering cells to produce soluble and secretable Golgi processing enzymes instead of naturally occurring membrane-bound enzymes. Cells are genetically engineered to express glycosyltransferases which lack both a membrane anchor and a retention signal. The resulting altered enzyme becomes soluble and secretable by the cell without losing its catalytic activity. Secretion of the soluble glycosyltransferase by the cell provides for increased production and simplified recovery of glycosyltransferases.

Abstract: A bolus volume means an unwanted infusion volume which arises when there is a partial blockage or blockage on the patient's side due to continuing delivery of the infusion, especially by means of an infusion pump, and may considerably endanger the patient when there is sudden administration thereof. In order to be able to divert and collect the bolus volume automatically, the invention proposes a container with an inlet (14) on the pump side and an outlet (5) on the patient's side. A displaceable piston (8) is mounted displaceably inside the container (1) and has a drilled passage (20) which connects a pressure chamber (21) on the pump side to a pressure chamber (22) on the patient's side. In the normal case which is shown, the infusion fluid flows through the drilled passage (20) in the displaceable piston (8). In the bolus case, because of the pressure difference from the pressure chamber (21) on the pump side to the pressure chamber (22) on the patient's side, the displaceable piston (8) is moved in the direction of the connector (5) on the patient's side and thereby exposes another lateral connector (23) which is connected to a low pressure reservoir which can be designed as drawn-up disposable syringe (27) whose syringe plunger (33) is locked in the drawn-up position by means of a clip (36). <IMAGE>

Abstract: The invention relates to a method for removing liquid from a mixture of liquid and solid matter. Said mixture is led over one or more casings by means of a conveyor belt which is pervious to liquid. In use a sub-atmospheric pressure is generated in the casings during a first period, in which said casing(s) and said conveyor belt are stationary with respect to each other, whilst at the same time a pressure is exerted on the mixture by means of rollers. During a period following on said first period a relative movement takes place between the conveyor belt and the casing(s), whilst during this period no sub-atmospheric pressure is exerted in the casings and no compressive force is exerted on the mixture by means of the rollers.

Abstract: In a starter system for an internal combustion engine, an input member of an overrunning clutch is provided with an annular shoulder surface abutting an annular end surface of a cylindrical boss portion of a reduction gear unit casing when the overrunning clutch is at a rest position, and a cylindrical sleeve portion extends from the annular shoulder surface towards the reduction gear unit so as to be closely fitted on the cylindrical boss portion of the reduction gear unit casing. Thus, water and other foreign matters are not only shut off by these mutually abutting annular surfaces, but also prevented from reaching this region by the cylindrical sleeve portion closely fitted on the cylindrical boss portion of the reduction gear unit. Also, the centrifugal force prevents water and other foreign matters from reaching this area when the starter is actuated and the two annular surfaces are not in contact.
